Companion functions

colorMatrix

@Stable fun colorMatrix(colorMatrix: ColorMatrix): ColorFilter

Create a ColorFilter that transforms colors through a 4x5 color matrix. This filter can be used to change the saturation of pixels, convert from YUV to RGB, etc.

Parameters
colorMatrix: ColorMatrix ColorMatrix used to transform pixel values when drawn

lighting

@Stable fun lighting(
    multiply: Color,
    add: Color
): ColorFilter

Create a ColorFilter that can be used to simulate simple lighting effects. A lighting ColorFilter is defined by two parameters, one used to multiply the source color and one used to add to the source color

Parameters
multiply: Color Color that will be added to the source color when the color filter is applied
add: Color Color used to multiply the source color when the color filter is applied.

tint

@Stable fun tint(
    color: Color,
    blendMode: BlendMode = BlendMode.SrcIn
): ColorFilter

Creates a color filter that applies the blend mode given as the second argument. The source color is the one given as the first argument, and the destination color is the one from the layer being composited.

The output of this filter is then composited into the background according to the Paint.blendMode, using the output of this filter as the source and the background as the destination.

Parameters
color: Color Color used to blend source content
blendMode: BlendMode = BlendMode.SrcIn BlendMode used when compositing the tint color to the destination
